Approved Document L, or Part L, of the Building Regulation sets the energy efficiency standards for building, providing guidance and requirements for achieving energy efficiency and reducing carbon emissions in new and existing buildings.
The recent updates to Part L introduce significant changes for housebuilders to accelerate the transition to a low-carbon future.
One of the notable changes is the fabric-first approach which prioritizes the building fabric’s energy efficiency reducing heal loss through walls, roofs, and windows. Of course, insulation will play a crucial role in meeting the immediate requirements as well as achieving longer-term ambitions such as the Future Homes Standard.
There are two routes to compliance using non-combustible insulation:
The first route, an interim design for interim standards, implies the upgrade to higher performance insulation while retaining existing cavity widths.
The second route, futureproofing future homes, will increase cavity widths in preparation for Future Homes Standard fabric while balancing wall, roof, and floor insulation through various compliance recipes.
Knauf Insulation is ready to help you help your customers. As the UK’s leading manufacturer of high performance, non-combustible insulation, they can support new builds and refurbishment projects in achieving compliance with Part L.
Their unique products are a combination of acoustic, thermal, fire safety, and sustainability benefits without compromising performance. They are naturally non-combustible made from mineral wool made in the UK from up to 80% recycled content, minimising carbon offset.
Moreover, Knauf Insulation can play a significant role in supporting new builds and refurbishment projects in achieving compliance with Approved Document L.
